undercover superhero. ( mario steel x reader )
gif belongs to me
Kaz was standing in the school hallway waiting for classes to start when you arrived. Oliver was the first to see you and voiced your arrival, causing Kaz to turn around, a groan leaving his lips when you called out to him, a smirk on your lips.
"Hey, baby brother." You held up a brown paper bag. "You forgot your butt ointment."
Your words earned a few stares, and Kaz laughed humourlessly, taking the bag and opening it to find his lunch inside. "Mom told me to drop it off on my way to work."
"Frozen yogurt for dinner?" He asked.
You nodded.
"And that's why you are my favorite sibling." He grinned.
You shook your head with a smile, turning to Oliver. "Are you coming over? I'll bring some for you too."
He nodded, "After trying to break up my mom and her boyfriend by making her think I need her, she's more unbearable than before."
You patted his shoulder as you knew how controlling his mother was. "You're welcome anytime. You know that."
"I can't believe you have a job. Who would hire you?" Kaz scoffed with a chuckle.
"I know, right?" You grinned. "Suckers."
Oliver shook his head as he looked between you both as Kaz suggested bringing him one of the cow-patterned caps you wore, opening his mouth to list the reasons why it was a bad idea. Number one being you would get fired. It wasn't often members of his family chose to stay on the legal side of life, and Oliver knew the only reason Kaz wasn't in jail with your siblings was because of your influence. He paused when he saw a familiar face arrive and hit Kaz's arm to gain his attention.
"Ow!" Kaz complained, his eyes widening when he saw Captain Atomic in a suit with a briefcase. "Yeow!" He laughed off when you raised an eyebrow in suspicion. "Well, it was great seein' you but you must be really busy -"
"Work doesn't start for another half hour. What? Are you embarrassed to be seen with me now?" You pinched his cheek, and he glared at you before he got an idea.
"You know what? Why don't I show you my locker? It's over here." Kaz pulled you away, and you followed him to his locker, raising an eyebrow when he opened it up.
"Gross, it smells like dirty gym shoes." You winced.
Captain Atomic approached Oliver when he called out to him. "What are you doing here?"
"There's been some reports about suspicious activity in this area. I'm here undercover to investigate." Captain Atomic replied.
"Suspicious activity?" Oliver asked.
The tall blond superhero nodded. "There appears to be a villain in the area who -"
"Your locker is lovely, but I better get going." Your voice drew their attention as you bickered with Kaz, who held up a comic book, shielding your view of Captain Atomic.
You took the comic and held it out to Oliver. "Don't give him any sugar." You looked at your brother with pursed lips. "He's had enough."
You noticed the man beside him and sent him a smile. "Hi, are you one of Kaz's teachers?"
He shook your hand. "Yes, it's my first day. I am Mr. Camito. And you are?"
"Y/N. Kaz is my brother. So I apologize for everything he says and does in advance."
He smiled softly, and you realized you were still shaking hands. "So...uh," You awkwardly released his hand. "Welcome to Logan High." You inwardly grimaced at your poor choice of words to break the ice.
"Thank you."
Kaz and Oliver shared a look, confused by the way you were looking at each other. Kaz stepped forward, interrupting your staring contest. "Shouldn't you be going now?"
You looked at your younger brother with a roll of your eyes. "Alright, alright, I'm going." You held your hands up as you backed away, sending the tall blond superhero a smile. "Have a good day, Mr. Camito."
When you were far enough away, Kaz looked up at Captain Atomic, "Dude, stop staring at my sister."
"I have never met such a doll before." He looked down at Kaz, raising an eyebrow. "Are you sure she is related to you?"
Kaz shook his head. "What is a dolly - actually," He held a hand up, "don't tell me. I don't wanna know." The bell rang, and the trio headed to history while Oliver caught Kaz up on why Captain Atomic was at their school.
Later that day, you were waiting outside the high school, and Kaz was walking out with Oliver by his side. The two approached you when they saw you were waiting.
"What are you doing here?" Kaz whispered lousily, gesturing with his hands.
"I thought I could drive you home. You know, I've been away a while, and, well, I thought we could hang out." You shrugged.
"We're busy." Kaz pulled Oliver away, and the latter sent you an apologetic smile as they left. He knew why Kaz had shot you down, but you didn't and hopefully wouldn't know the truth about where they were going. It was safer that way.
You sighed, putting your hands in your pockets, turning to the tall blond when he appeared beside you. "Is everything alright?"
"Yeah, I'm fine. So, how was your first day?"
You headed to the parking lot, purposely walking slowly to your car, which was preferable for you both. "Interesting." He said, choosing his words carefully.
A giggle left your lips, remembering well how chaotic high school used to be. "I can imagine."
He smiled at the sound of your laughter. "How was your day?" He asked, eager to keep the conversation flowing.
"Well, the fro-yo machine practically exploded this morning, and I've got twenty melting frozen yogurts in my car, so..." You trailed off with a smile. "Say, you wouldn't..." You hesitated as you stopped next to your car, starting to wonder if he was just being polite. "Never mind."
"What is it?" He asked, eyebrows furrowing.
"You wouldn't want one, would you?"
It took him a moment to stop a wide grin from forming on his lips and to act more collected. "I would love one." He replied with a controlled smile, but when you turned around he allowed a grin to form on his lips before suppressing it once more, thanking you when you held out a frozen yogurt to him with a spoon.
You spent over two hours in the parking lot, sitting on the hood of your car, talking to a man you had no idea was a superhero, and not just any superhero, a superhero who was recently released after being trapped in a wormhole, returning decades from his own time. But there was one thing you did know when you went your separate ways. You liked him...a lot.
The next day Kaz was baffled and suspicious of why Captain Atomic asked questions about you, about what you liked and didn't like, but his intentions became clear when he asked what kind of men you were attracted to.
"No!" Kaz exclaimed, pointing at him. "You cannot date my sister."
"Why not? She is a swell gal." He placed his hands on his hips, a smile on his lips at the thought of you.
"This isn't happening." Kaz turned to Oliver. "Tell me this isn't happening."
"Y/N says I shouldn't lie." Oliver shrugged.
As if on cue, you appeared with two frozen yogurts in your hands. "Hey, guys. You ready to go?"
You looked at Captain Atomic, who stepped forward with a smile. "Hello."
"Hey." You returned the smile.
"Okay, stop with the googly eyes!" Kaz complained, throwing his hands up in the air. "And give me my fro-yo." He took the two frozen yogurts, and the two teenagers walked to your car.
After listening to Kaz complain about how weird it was, Oliver asked, "Why can't they get together?" The two looked over at where you were laughing at something Captain Atomic said, the blond superhero smiling down at you. "She seems to really like him, and he likes her."
"First of all, he is not that funny." Kaz pointed at you. "And second, imagine the family get-togethers."
When you walked to your car, you were smiling, and the three of you got into your car, Kaz asking you what you were so happy about as he buckled his seatbelt.
"I have a date."
"Oh no, you cannot go on a date with Captain - with my teacher." He quickly corrected.
You looked at him as you drove off, "I can. And I am. So deal with it."
Kaz looked at Oliver for backup, but the boy only shrugged in response, earning a groan from his friend as he turned to look at you. "I will hate you forever," Kaz said, hoping to make you change your mind.
"I'll live." You patted his shoulder with a smile, irking him further.
That night you were getting ready for your date when you got a phone call from the principal. You were shocked that Kaz was facing a suspension for his behavior and agreed to meet within the half hour. You had two hours before your date, so you were sure you had enough time, and after leaving Kaz an angry voicemail, you drove to the high school.
You were confused when you found it deserted, calling out to Principal Howard moments before you were knocked unconscious. When you didn't arrive for your date, Captain Atomic, filled with confusion and disappointment, went to Mighty Med, where Kaz and Oliver were. Kaz was shocked that you hadn't turned up, and when he saw how it affected Captain Atomic, he remembered the voicemail you left him.
"Wait," He took out his cell phone. "She said something about meeting the Principal about a suspension. That was two hours ago."
Captain Atomic listened to the voicemail, eyebrows furrowing. "You better get your butt home early tonight. I swear - a suspension, Kaz? Are you insane?" He raised an eyebrow when you screamed in frustration, looking at Kaz when the message ended.
"You are facing a suspension?"
"I didn't do it. But that's beside the point." Kaz said, and Captain Atomic held his hands up, not questioning him further.
"We should check the school," Oliver suggested.
"I agree." Captain Atomic nodded.
"Wait!" Kaz stopped the superhero before he could leave, "If you go in that," He gestured to his costume, "she will know you are a superhero."
"Y/N could be in danger. And I'm not prioritizing an outfit change over her life."
Kaz looked at Oliver when Captain Atomic left. "Alright, maybe he's not so bad -" Oliver rolled his eyes and pulled him out of Mighty Med, following Captain Atomic out of the hospital.
The school was deserted when they arrived, and the trio split up, searching for any sign you were there. Oliver swallowed thickly when he found your cell phone and turned to the two, holding it up. "Uh, guys."
Kaz licked his lips nervously, seeing the screen was broken. "Alright, alright -"
Captain Atomic placed a hand on his shoulder in the act of reassurance to calm him down, sensing he was beginning to panic. "It's alright." He looked around the hallway with newfound determination in his eyes, "We'll find her."
You squirmed in your chair, groaning from the pain in your wrists from the rope keeping you tied to the chair. Kaz had briefly told you about his friends, and when you were tied up beside the teenage girl, you knew she was Jordan. What you weren't expecting was for her to claim she was right - that superheroes did exist.
"Shut up!" The Principal, or as he revealed Unit-238, shouted in exasperation to the teenager, who quickly turned silent. "And now, you will be destroyed, and no one can stop me!"
The classroom door burst open, and your eyes widened when you saw Mr. Camito arrive, wearing a red and blue costume with a large A on his chest. "Not so fast."
Kaz and Oliver ducked into the room when a blast was sent their way, and you gasped when it hit Captain Atomic who backed into the hallway, Unit-238 chasing after him. Once Kaz untied you, you rushed to the hallway with the three teenagers hot on your heels.
Unit-238 held his right arm out, pressing a button on the exposed mechanics blasting at Captain Atomic who did a back flip, causing the lockers behind him to lose their doors and their contents. His feet landed on the wall above the lockers and he pushed himself toward the robot and the two grappled for a moment until Captain Atomic pinned him against another row of lockers.
"There's a perfectly reasonable explanation for this...Jordan, Oliver has a crush on you."
"How is that a reasonable explanation for what's happening?" Oliver replied.
Unit-238 attempted to aim at Captain Atomic and you quickly moved Oliver aside to open a locker, blocking the blast as it shot towards you. Kaz grabbed your hand and pulled you with him as he and Oliver rushed for cover. "Jordan, run!"
You held onto the bars of the staircase when Unit-238 managed to push Captain Atomic back, firing at the blond superhero who ducked, the blast bouncing off the locker and hitting a stunned Jordan.
You moved to help but Kaz pulled you back down and he and Oliver rushed to lift Jordan and bring her to your hiding spot. You looked at the robot as he aimed his arm at Captain Atomic who spun a yo-yo, creating a shield that with each blast was weakening.
"On a scale of one to ten how grounded am I?"
You turned your head, sending Kaz a scowl before looking at Oliver when he spoke.
"We've got to help him."
When Captain Atomic stumbled, you stood up and called out to the robot who turned. You quickly ducked when he fired at your head, the blast hitting the wall.
The distraction gave Captain Atomic the time he needed to get back on his feet. He darted towards the robot and swept his legs, causing him to flip and land on his stomach. Captain Atomic hauled the robot to his feet and just when you thought it was all over, Unit-238 broke free and used his body to push the superhero against the lockers.
"We've gotta stop him!" Kaz pulled you down when you tried to stand up. "Not you."
"Do you have a better idea?"
Kaz looked at you, surprised you had raised your voice at him, and for the first time he realized how scared you were. But not for yourself, for Captain Atomic and he realized just how much you had grown to care for the superhero.
"Wait!" Oliver turned to Kaz, "Remember that comic about the rise of the cabal of chaos? I think Principal Howard is the same model android."
"And that helps us how?" You asked.
Kaz called out to the blond superhero, "Captain Atomic, remove the flash drive from behind his ear!"
"Brilliant! One question." The Captain replied as he held the robot in a headlock. "What's a flash drive?"
You screamed, covering your mouth when he was blasted into a row of lockers, his distraction giving the android the opening he was looking for.
"No!"
When you tried to stand up, Kaz held you down as the android aimed his weapon. Kaz and Oliver quickly got to their feet and tackled the android to the ground. Oliver helped hold him down while Kaz removed the flash drive.
When you saw the android stand up, your brother jumping on his back to stop him from blasting Oliver, you got to your feet as Kaz broke the hard drive in the robot's ear, causing its head to blow off and land on the ground. You watched as the body fled the school and approached them as they looked down at the head.
"Well, we better take our headmaster to Mighty Max prison for detention." Oliver spoke up. When he received stares, he added, "Cause he's just a head and detention is another word for..."
"Yeah, we got it."
Kaz and Oliver rushed over to help Jordan when she woke up and you looked at Captain Atomic, biting the inside of your cheek nervously, "So...you are -"
"Captain Atomic!" Jordan pointed at the blond superhero and you both turned to look at the teenagers.
"Yeah, not now." Kaz led her out of the school with Oliver, giving you both privacy to talk.
"Does that mean everything was a lie? Is your name even Mario Camito?" You asked.
"It's Steel." He said. "I would have told you..." He picked up a backpack and placed the android's head inside, "I was hoping for more time to get to know you before I revealed my secret."
You placed a hand on his arm, "It's fine. I get it. You can't go blabbing about who you are. I'm just glad you're okay." You smiled softly.
Relieved by your understanding, he asked, "So...does this mean you wouldn't be opposed if I proposed we rescheduled our date?"
"I'd like that." You nodded.
He smiled for a moment before looking at the former Principal. "I should -"
"It's okay." You reassured. "Another time."
He smiled softly before leaving with Unit-238, and you followed, standing with Kaz and Oliver. "Here's your phone." Kaz winced, holding out the smashed cell phone.
You thanked him, putting an arm around him. "Let's have a little talk." You grabbed Oliver's shirt before he could turn away. "Let's start with how you know about superheroes..."
Two hours later, you were cooking to help your parents, who would return from work soon, while Kaz and Oliver played video games upstairs. Kaz came down for two sodas and to check on how you were.
"So...are you mad at me?" He asked.
You stopped stirring the sauce, turning to him. "Why would I be mad?" You approached him with a gentle smile. "You save people who save people so they can continue saving people. As far as jobs go, you hit the jackpot." You placed a hand on his shoulder. "I'm proud of you. Just...no more surprises."
Kaz scratched the back of his neck, "Then I should probably tell you that no one is coming for dinner. They all went to the diner on ninth."
There was a knock on the door, and your eyebrows furrowed. "You might want to get that," Kaz said, moving towards the staircase as you went to answer it, shocked to find Mario Steel, better known as Captain Atomic, on your doorstep.
"Hi." He greeted.
"Hi." You stepped aside to let him in and smiled at his casual attire. "What are you doing here?"
"Kaz invited me. I hope that's okay."
You realized then that your younger brother had arranged for the house to be empty so you could have your date. You smiled at the superhero who returned it.
"Yeah, it's definitely okay."
Several minutes later, the two teenagers looked up when you knocked on the bedroom door, walking over with a smile, two dinner plates in your hand. "Thank you." You mouthed as you left, and Kaz nodded, smiling faintly.
As you sat at the dinner table across from Mario, you sent him a small smile. "It's not Rizzoli's but -"
"It's delicious." He cut you off with a smile. Your smile grew when he took your hand across the table. "I have to say, you are the most stunning woman I have ever had the honor to lay eyes upon."
You blushed at his words, "You're not so bad yourself, Captain."
He smiled, shyly glancing at the table for a moment.
A week later, when you picked up Kaz and Oliver to school, they showed you where Mighty Med was, giving you a tour of the hospital.
The tour was nearing the end when you returned to the reception, where you found Mario talking to the Crusher.
You greeted him with a smile, "Hello, Captain."
He smiled as he turned around. "Y/N. How was the tour?"
"Pretty sweet. I shrunk Blue Tornado." You grinned when he raised an eyebrow in shock. "Kidding."
He chuckled, having grown used to your jokes, and leaned down to kiss your forehead.
"Oliver, they're doing it again!" Kaz complained, gesturing to where you were standing next to Mario, his hand on your back, staring at each other with smiles on your lips.
The two teens left, and you giggled when Kaz covered his eyes, walking into a wall.
"I think he's getting used to the idea. That sounded less disgusted than usual." You commented.
"So, he won't mind if I did this..." He placed a hand on your cheek, leaning down to kiss you tenderly.
You pulled away when you heard Kaz shout, "Oh, come on!"
You looked at your brother, knowing he was, in fact, supportive of your relationship. Mario suppressed a smile, looking down at you when you giggled into his chest.
When you found out the truth about his secret identity, you knew life wouldn't be the same, but as you looked up at him, finding him smiling down at you, you knew it was only for the best.
